Guidetti's agent Per Jonsson told Voetbal International last week that a return to Feyenoord remains a distinct possibility.

"He liked his stay at Feyenoord and enjoyed putting in strong performances for them," said Jonsson.

"Joining them again is definitely an option, but there are more possibilities, we are going to explore all options without rushing and we will surely come to a decision before the transfer window ends at the end of the month."

Realistic

But the Dutch club have moved to dampen speculation linking the Swede with a return to De Kuip.

"At the last moment, anything can happen but we are not assuming the return of John is realistic," said Feyenoord technical director Martin van Geel.

"We do not know what City want - and besides, he needs time to recover from his injury."
